Outlook 2010 reports it can't open pst file(s) RRS feed

  • Question

  • After the Windows 10 Fall Creators update, and a short short update of Outlook 2010, Outlook reports it can't open x.pst files. I've tried various pst files from the current working file to backups.
    I've tried removing the pst files and letting Outlook create a new pst (so that I can import from the old pst and that new pst will not open.

  • Hi Rick,

    How many users are affected by this issue in your organization?

    Where are the .pst files stored? On your local drive or on a network share?

    >>I've tried removing the pst files and letting Outlook create a new pst (so that I can import from the old pst and that new pst will not open.

    In which folder did you create the new pst file? What if we try creating a new .pst file to another location, such as Desktop?

    Regards,

    Steve Fan

  • I ran ScanPST.exe but it locked up. Bear in mind what I said above. I've tried various other pst and none of them will work. It is hard to imagine that all of them are corrupted.

    Outlook will not load so I cannot try the reference 2.

    The error messages so far have differed slightly. The latest one reads:

    Cannot open your e-mail folders. The C:\<Path to the .pst file> cannot be opened. Then Outlook closes without further ado.

    I've also tried moving the pst files elsewhere and letting Outlook create a new pst but that does not work.

  • I am the only affected user. I am the only user who has Windows 10 and this happened right after a Windows 10 Fall Creators update followed by an unnamed update to Outlook which I think was part of the Windows 10 update.

    The pst are located on my local C drive in the standard location for Outlook pst, Documents/Outlook Files. The suggestions I found on the web for creating a new pst was to empty the Outlook Files folder and Outlook would create a new pst in this folder.

    Okay so I have a pst created on my desktop. What is the next step to get my files from the old pst to the new one? TIA

  • Hi,Rick

    Based on your description, your Outlook PST file may be corrupt.

    The Outlook PST file format is very complex. It starts with a file header containing the meta information of the whole file, followed by several parts containing the actual data. You can find more detailed information about the Outlook PST file format by searching on Google with the keyword “Outlook PST file format”. If the file header containing the meta information is corrupt, or any follow-up parts are damaged or corrupted, then you will not be able to open the file correctly with Outlook. In such a case, the first step is to try to use the built-in repair or recovery function in the Outlook, to see if it can repair or recover corrupted Outlook PST file for you. If not, then you need to resort to a third-party Outlook recovery tool to scan the corrupted file and retrieve all recoverable data for you. It is also possible to find a data recovery expert or company to do the task, but in most of the cases, they will also use a third-party tool to do the recovery for you.

     

    The main difference between using the software by yourself and by a third-party service company is:

    (1)    The company is familiar with the data recovery industry so he knows which software is the best one. While you need to search and compare the software online by yourself, which is time-consuming.

    (2)    The company purchases the software for multiple usages, while you purchase the software for one-time usage only. So normally the service fee may be cheaper than the license fee for the software.

    (3)    DIY will keep your data confidential while do the recovery via a company may cause data breach.

     

    First, the Microsoft offical tool scanpst, also called Inbox Repair Tool, can repair the PST file, you can refer the following articles:

    http://support.microsoft.com/kb/272227

    https://support.microsoft.com/kb/287497

     

    If the above method does not work, then you can try DataNumen Outlook Repair at:

     

    https://www.datanumen.com/outlook-repair/

     

    I have used the tool in the past and it helps recovering some valuable data for me. The tool has a free demo so that you can try to see if it works on your file or not before you buy.

     

    Hope this will help. Good Luck!

  • Good morning guys. Yes my description may have been misleading but I did not know how to articulate the problem.

    Turns out, the profile was corrupted (for lack of a better word). Once I created a new profile, and referenced the .pst file in question, I was up and running. Your suggestions helped eliminate causes and narrow my focus. Thanks!!
